Description

Dark matter detectors using liquid xenon have reached the tonne-scale with XENON1T, giving them good sensitivity to supernova (SN) neutrino signals via coherent elastic neutrino-nucleus scattering. We perform an S2-only analysis of the expected supernova neutrino signal for four different SN progenitors with different masses and nuclear equations of state in existing and upcoming dual-phase xenon experiments. We show that a SN burst can be detected at more than 5 sigma significance up to 25 kpc, 40 kpc and 70 kpc from Earth for XENON1T, XENONnT/LZ and DARWIN sized detectors. We also show that the SN neutrino light curve, neutrino differential flux and total energy emitted into neutrinos can be reconstructed with small error bars. As xenon detectors are sensitive to all neutrino flavours, they provide complementarity information to traditional neutrino detectors that are sensitive to a single flavour.
